Abstract
Evaporator assemblies, vapor chamber assemblies, and methods for fabricating a vapor chamber are disclosed. In one embodiment, an evaporator assembly for a vapor chamber includes an evaporator surface, an array of posts extending from the evaporator surface, and an array of vapor vents within the evaporator surface. Each vapor vent of the array of vapor vents is configured as a depression within the evaporator surface. The evaporator assembly further includes a porous layer disposed on the evaporator surface, the array of posts, and the array of vapor vents.
Claims20
An evaporator assembly for a vapor chamber, the evaporator assembly comprising:
- an evaporator surface;
- an array of posts extending from the evaporator surface;
- an array of vapor vents within the evaporator surface, wherein each vapor vent of the array of vapor vents is configured as a depression within the evaporator surface;
- and
- a porous layer disposed on the evaporator surface, the array of posts, and the array of vapor vents.
An assembly comprising:
- an evaporator assembly comprising:
- an evaporator surface;
- an array of posts extending from the evaporator surface;
- an array of vapor vents within the evaporator surface, wherein each vapor vent of the array of vapor vents is configured as a depression within the evaporator surface;
- and
- a porous layer disposed on the evaporator surface, the array of posts, and the array of vapor vents;
- and
- a condenser plate comprising a condenser surface, wherein the condenser surface is bonded to a top surface of the array of posts such that the evaporator assembly and the condenser plate define a vapor chamber.
A method of fabricating a vapor chamber, the method comprising:
- forming an array of posts and an array of vents in an evaporator surface;
- applying a metal powder comprising metal particles to the evaporator surface, the array of posts, and the array of vents;
- sintering the metal powder to form a porous layer;
- and
- bonding a condenser surface of a condenser plate to a top surface of the array of posts.
